4 Introduction This document contains the hardware and software requirements for implementing the PowerSchool 8.2 Student Information System, including PowerTeacher and ReportWorks, and is designed to guide customers with fewer than 15,000 enrolled students. The equipment and resources listed herein are required to ensure proper system usability and the highest quality user experience possible. Support for Windows Server 2012 R2 operating system Support for Mac operating system and Safari 8 browser PowerSchool 8.2 requires 64-bit, server class hardware using a 64-bit Windows operating system of either Windows Server 2008 R2 SP1 or Windows Server 2012 R2 (English Version). PowerSchool 8.2 runs with an Oracle 12c database only, and no longer supports Oracle 11g. For districts larger than 15,000 enrolled students, a more tailored configuration may be warranted. For consultative assistance with PowerSchool configurations of this nature, or to learn more about Pearson s hardware packages and services for all enrollments, please contact your Pearson sales representative at , or TSGHelpDesk@Pearson.com Introduction 4

5 General Requirements The following requirements must be implemented with every PowerSchool configuration. Dedicated Hardware: All servers in the production environment must be dedicated solely to operation of the PowerSchool product and its complementary components, such as PowerTeacher and ReportWorks. The only exception to this rule is the image server (see below). Server Class: All hardware referenced in this document must be server class hardware, except the PowerScheduler client and user workstations. Dynamic Port ranges: The default dynamic port range is in compliance with Microsoft Windows Server 2008 R2 requirements. Image Server: All environments must include an image server to serve the graphical files in PowerSchool. The image server may be configured on the same, single computer if the active student count is fewer than 3,000 students. For districts with an active student count over 3,000, a separate image server is recommended. For districts with an active student count over 7,000, a separate image server is required. The server used for these images may be an existing web server and does not need to be dedicated to PowerSchool image serving. For enhanced performance, the image server may reside on a dedicated server, but this is not a requirement. Load Balancing: Array environments of two or more application nodes must be served by a load balancer, which directs the user traffic and balances the load among all nodes in the array. Although neither supported nor certified by PowerSchool, any hardware or software load balancer, when configured properly, should have the potential to operate successfully within the production environment. PowerSchool does not endorse any particular manufacturer, and the load-balancing provider would provide support. For more information, please refer to the Load Balancer Requirements and Configuration Guide available on PowerSource. Windows Operating System: The entire PowerSchool deployment, inclusive of all application nodes and the database server, must run on the same version and edition of Windows Server. The following versions and editions of Windows Server are Supported: o Microsoft Windows Server 2008 R2 SP1: Standard Edition Enterprise Edition Datacenter Edition Windows Web Server Edition o Microsoft Windows Server 2012 R2: Standard Edition General Requirements 5

6 Datacenter Edition Note: The Server Core installation option is not supported. For Windows Server 2008 R2, most servers can run the Standard Edition, which covers most production environments up to and greater than 15,000 students. Windows Web Server 2008 R2 may also be used, although this edition caries some constraints, such as its inability to be used as a file server. For configurations where the database server needs more than 32GB RAM, either Enterprise Edition or Datacenter Edition of Windows 2008 R2 SP1 is required. Important Note: Mainstream support for Windows Server 2008 R2 SP1 ends in early If you are not licensed for Extended Support by Microsoft you must upgrade to Windows Server 2012 R2. Microsoft licensing provisions require specific licenses when most users connect to a Windows server. A Client Access License (CAL) is required for each teacher and administrator who accesses PowerSchool, since Microsoft considers them internal users. The CAL can be either a "Device" CAL to cover the number of workstations used by teachers and administrators who access PowerSchool, or a "User" CAL to cover each individual teacher and administrator who accesses PowerSchool. An External Connector License (ECL) is required for each PowerSchool server that serves parents, guardians, and students since they are considered external users by Microsoft. Exceptions to these two guidelines include the following: o PowerSchool Software as a Service customers (Pearson manages the licenses). o Districts that license Active Directory for their users for Windows 2008 R2 and Server 2012 R2 o Districts that choose to deploy Windows Web Server 2008 R2 instead of Windows Server 2008 R2 Standard, Enterprise, or Datacenter Editions. There is no Web Server edition for Windows Server Important Note: CAL and ECL licenses purchased for Windows Server 2008 are not transferable to Windows Server Pearson recommends that you contact Microsoft or your district s software vendor for details regarding Microsoft software licensing. General Requirements 6

11 Document Attachment New for Release 8.0 PowerSchool Document Attachment is a new feature with PowerSchool Release 8.0 that enables administrators to attach documents to the student record in the administrator portal of PowerSchool. If you intend to utilize this feature, you will need to consider the impact on your data storage and network bandwidth needs. To estimate your basic storage needs, there are three primary considerations: Estimated number of documents to be attached per student Estimated size of documents to be attached 5% allocation for attachment metadata files For example, if your district has 1,000 students, you anticipate an average of 10 attachments per student, and you anticipate the average attachment file size to be 300 KB, then you would need a minimum of approximately 3 GB of storage for the attachment of documents to the student record: Example Calculation Total Attachments Estimated Storage 10 attachments x 300 KB attachment size 3,000 KB per student 3,000 KB x 1,000 students 3,000,000 KB for all students (3,000,000 KB / 1,048,576 KB per GB) * (1 + 5% for attachment metadata) 3 GB storage To calculate your true storage needs, there are additional factors to consider: Annual rate of increase of student population Attachment retention and archival policy (for example, the number of years after graduation that an attachment saved) Data back-up strategy implemented File compression or encryption implemented on the storage device All of these factors should be considered to ensure a seamless and uninterrupted utilization of PowerSchool Document Attachment. Pearson also recommends that you review your network bandwidth if implementing this feature, since files of varying sizes being uploaded and downloaded throughout a typical day may demand increased network bandwidth. Note: PowerSchool Document Attachment requires the implementation of SSL. For more information on implementing SSL for PowerSchool see Knowledgebase article 8476 available on PowerSource. Document Attachment New for Release

12 General Recommendations The following recommendations are not required for a successful implementation of PowerSchool, but are strongly recommended for reasons pertaining to data security, redundancy, performance, and efficiency. Data Security: While Pearson undertakes extra measures to ensure we deliver secure applications, we strongly recommend that PowerSchool customers take additional and deliberate measures to secure their PowerSchool deployment. In addition to physical security and a strong password management regiment, we also strongly recommend securing of data in transit and at rest with standard encryption technologies: Data In Transit: Secure Socket Layer (SSL) is the standard security technology for establishing an encrypted link between a web server and a web browser, and ensures that all data passed between them remains secure and private. For more information on implementing SSL for PowerSchool see Knowledgebase article 8476 available on PowerSource. Data At Rest: Based on Pearson performance benchmarking, the most costeffective and comprehensive tool for securing PowerSchool data at rest is utilization of Microsoft BitLocker to encrypt both the database server, and all application nodes. Microsoft BitLocker is a delivered component of Windows Server 2008 R2, and has been shown to have minimal impact to overall performance. Alternatively, many storage devices also have encryption capabilities that can be leveraged in addition to, or in place of, Microsoft BitLocker. Redundancy and Performance with RAID: Redundant Array of Independent Disks (RAID) is a standard technology that provides increased storage reliability through redundancy, and in some configurations results in increased performance. While Pearson recommends a RAID 10 (1 plus 0) for increased redundancy and performance on the database server, larger districts requiring 1 TB of storage or more may find RAID 5 a suitable alternative at a lower cost per disk. Network Bandwidth Guidelines: Network bandwidth will vary by district based on a myriad of different factors such as network type and configuration, and district-by-district usage patterns. The following data can be used as a starting point for calculating your district-level needs, and is based on network traffic of sampled PowerSchool pages: o o o Up to 3,000 Students: 1.52 Mbs 3,000 to 7,000 Students: 3.55 Mbs 7,000 to 15,000 Students: 7.61 Mbs General Recommendations 12

13 Client Software Support Tablets PowerSchool 8.0 supports the following tablet for standard delivered web pages. Device Operating System Notes Apple ipad Mini ios 6 or greater All generations supported Apple ipad ios 6 or greater All generations supported 7" 10 Android Tablets Microsoft Surface Tablets Android or greater Windows 8 or greater minimum resolution minimum resolution Note: Amazon Kindle Fire and Barnes & Noble Nook are currently not supported. Additionally, some PowerSchool features such as Visual Scheduler, ReportWorks Developer, and creation of seating charts are not intended for use on a mobile device, and are therefore not supported. Laptops and Personal Computers PowerSchool 8.0 supports the following client operating system and browser combinations, up to the latest patched version. Older client operating system and browser versions that were once supported may continue to operate properly, but are no longer supported. Important: The following combinations are also supported for PowerScheduler. Windows 7 Internet Explorer 10 (Traditional and Metro) Latest two versions of Firefox (including most current ESR release) Latest two versions of Chrome Windows 8 Internet Explorer 10 (Traditional and Metro) Internet Explorer 11 Latest two versions of Firefox (including most current ESR release) Latest two versions of Chrome Client Software Support 13

Note: Pearson does not support Compatibility View on Internet Explorer. Note: Visual Scheduler may be used with any certified or supported browser as indicated in this document. However, due to the use of more technically advanced browser features in the Visual Scheduler, Pearson believes the best user experience from both a functional and a performance perspective will be with the most current versions of Firefox, Safari, and Chrome. Note: Districts using Mac OS X 10.7 or greater for scheduling should refer to Knowledgebase article available on PowerSource for installation instructions. Client Software Support 14

16 Notes Non-Production PowerSchool Environments Customers may choose to set up a non-production environment for various purposes such as training, testing, development and off-line/snapshot reporting. Since these environments typically are not receiving significant user load, you may configure these environments with the database, application node, and image server residing on a single server an all-in-one configuration. Plan for upgrading your non-production environment hardware to a Microsoft Windows configuration using 64-bit hardware with a Windows Server 2008 R2 64- bit Standard Edition operating system. Virtualization of PowerSchool Environments Server virtualization is software technology that uses a physical server and divides its total resources across many virtual machines (VMs). Server virtualization allows technology administrators to consolidate physical resources, simplify deployment and administration of resources and environments, improve disaster recovery, and reduce power and cooling requirements. For districts up to 15,000 enrolled students, the district may utilize virtualization for the PowerSchool application node server(s), the PowerSchool database server, the combined application node and database server, and the PowerSchool image server. In all cases, each virtual machine must have server specifications that are at least equal to the stated physical requirements in this document. For more information, please refer to the Virtualization Hardware and Software Requirements and Configuration Guide available on PowerSource. Note: Pearson does not recommend or endorse any particular server virtualization software. For support, please contact the manufacturer of the server virtualization software that you choose to implement. Note: Pearson provides application support for PowerSchool when it is deployed within a virtualized server environment. However, Pearson does not provide direct support for the configuration and performance of virtualization technology environment itself within the definition of Pearson Technical Support. Performance Assumptions The PowerSchool Quality Assurance and Performance Team routinely tests the server resource requirements specified in this document. In executing this performance testing, we make several assumptions that reflect system usage of a Notes 16

17 typical customer, in several configurations ranging from 3,000 to 15,000 enrolled students: 20 students for every teacher. 100 students for every administrator. On average, 25 percent of the total Teacher and Administrator user population is actively using the system at any given time during the school day. Five school years worth of complete historical data in addition to the district data for the current school year. These assumptions may or may not reflect your business model. They are provided solely to add context to our system requirements so that you may build a configuration that enables you to achieve system performance that meets your expectations. Disk Space Requirements The minimum required disk space listed in this document on the server containing the Oracle 12c database, data-files, and backups is calculated based on the following factors, which are applicable to all district regardless of student enrollment: Daily accumulation of district data for the current school year. Five previous school years of complete historical data. Five previous school years of partial historical data (grade information). Disk will eventually contain five years of data for future school years. Disk space requirements for installations of Windows 2008 R2 SP1 and Oracle 12c. Standard logging configuration and backup regimen. Notes 17
